The High Back Mesh Ergonomic Office Chair with Retractable Footrest delivers a balanced blend of structured support, functional flexibility, and understated professional styling for a range of seated work and rest settings. Its visual profile features a tall, contoured high-back silhouette paired with fixed curved armrests, a wide five-star base, and smooth rolling casters, creating a streamlined, unobtrusive look that aligns with both commercial and residential workspace aesthetics. The breathable woven polyester mesh backrest is framed by 20% fiberglass-reinforced PP plastic, with an integrated fixed contoured central lumbar support that aligns with the natural curve of the lower spine. The seat uses a 55 kg/m³ high-density polyurethane foam core 80mm thick, topped with a durable surface for long-wear comfort. The chair’s structure includes a glass-filled nylon five-star base with 3mm wall thickness, a Class 4 steel gas lift with 50mm outer diameter and 95mm stroke, 60mm diameter PU tread casters with PA hubs, a 2.5mm thick stamped steel tilt chassis, and a retractable footrest with a molded PP surface and steel support rails. For adjustability, the chair offers pneumatic seat height adjustment with 95mm travel to a maximum 735mm floor-to-seat height, lockable recline at three positions (90° upright, 115° for focused work, 135° for napping), 360-degree continuous swivel, a pull-out footrest that extends 300mm from the seat front for leg support, a height and angle adjustable curved headrest with 50mm vertical travel, and a knob-controlled tilt tension setting calibrated to match user weight. Key performance metrics include a 159 kg recommended maximum user weight, 1136 kg five-star base static load capacity, 120,000-cycle gas lift durability, and 40,000-cycle caster rolling durability, with a maximum net weight of 19.5 kg. The chair is well suited for open-plan office workstations supporting 8-hour daily seated tasks, home office setups compatible with standard 760mm height office desks, private managerial offices requiring extended upper back and neck support, meeting and conference rooms where smooth movement supports collaboration, and dedicated nap break spaces for short workday rest periods, fitting users up to 188cm tall via its adjustable seat and headrest. For procurement, note each unit ships in two cartons with a total packaged gross weight of 23 kg and 0.26 m³ total volume, requires 40 minutes of assembly per set, and is sold as an unbranded model under the SKU ERG-OFF-MESH-68B-FR, with no proprietary branding to allow flexible deployment across different workspace design schemes.
